SIBO Breath Testing

SIBO (Small Intestinal Bacterial Overgrowth) is a condition where too many bacteria grow in the small intestine, causing bloating, gas, diarrhea, and abdominal discomfort. The breath test is a simple, painless way to detect SIBO — you drink a sugar solution (lactulose or glucose) and breathe into a collection device at regular intervals. The gases in your breath tell us if bacteria are overgrowing in the wrong place.

SIBO is often the hidden cause behind chronic bloating, IBS-like symptoms, and malabsorption. Identifying and treating it can bring dramatic relief. The breath test is completely non-invasive and the most widely used method for diagnosing SIBO worldwide.

1. You arrive fasting and provide a baseline breath sample
2. You drink a small amount of sugar solution (lactulose or glucose)
3. You breathe into a collection bag every 15–20 minutes for about 1.5 hours
4. The samples are analyzed for hydrogen and methane gas levels
5. Your doctor reviews the results and discusses the findings with you
